IMPROVEMENT IN STEAM-GENERATORS.

The Schedule referred to in these Letters Patent and making part of the same.

cation, in Which- Figure 1 is a side elevation. Figure 2 is an end view. Figure 3 is a top view.

Figure 4 is a sectional view oi the valves H H H.-

lLike letters of reference indicate like parts in the diierent iignres.

My improvement consists in providing a receiver, situated between the boiler and the engine, in which saturated and superheated steam, and also a portion of the exhaust steam are combined, the said receiver being provided with suitable Acheck-valves, to prevent back pressure on the boiler.

I will proceed to describe myl'pinvention.

A is the boiler.

B, theJ super-heater.

C, the receiver.

I) is a pipe, leading from the boiler to the superheater, having a check-valve at E.

F is a pipe, connecting the snperheater B with the receiver C, through the valve H.

- A pipe, G, connectsythe boiler A with the receiver C, through the valve H.

One end of the pipe I connects with the receiver O, through the valve H; the other end is bent downward,'and enlarged so as to forma'funnel, which is encased in an enlarged portion of the exhaust-pipe J, leaving suiicient space around it foi" the escape of steam.

The valves H H' H are constructed as seen iniig. 4, with a stop-cock at K, and a check-valve at L.

M is a pipe, which connects the superheater B with the boiler, below the water-line, and is furnished with a stop-cock N.

O is a pipe, which connects the receiver C with the p boiler, and is 4provided with a stop-cock, I.-

'Ihe pipe which leads to the engine is connected with the receiver O'at Q.

W'hen the engine is not working, the stop-cock P, inthe pipe O, is-opened, to allow the mixed vapors to pass from the receiver C back into the boiler.

The pipe M is used to convey water from the yboiler to the superheater.

What I claim as new, and desire to secure by Letters Patent, is-

1. The receiver C, combined as herein set forth, whereby the saturatedand superheated steam is commingled, as above Vset-forth.

2. The pipe D, super-heater B, and intermediate devices, in combination with the receiver O, substantially as shown and described.

3. The arrangement of the devices whereby to ex- Y haust steam into the receiver G, as set forth.

The above specification of my invention signed by me, this 4th day of February, 1869.
